Abstract
A tool with an engine, a shaft, and a recoil starter pulley coupled to the shaft for rotation about an axis. A starter pull rope for winding and unwinding around the recoil starter pulley. An air chamber shroud extending about at least a portion of the pulley, the rope extending from the pulley through the shroud. A tube enclosing a portion of the rope and extending from a location adjacent to and aligned with the pulley to a location at an exterior of the shroud that is axially offset from the pulley. The tube may have flared ends to reduce gradual wear of the rope. The tube alters a trajectory of the pull rope to be substantially offset from the plane of the starter pulley so as to avoid interfering with neighboring structures inside the tool.
